Sensitivity of novel markers CRMP1, DDC, GABRB3, ISL1, KIF1A, and PHOX2B was evaluated by seeding NB cell line LAN1 and NMB7, ranging from 1 to 104 cells in 107 normal mononuclear cells (MNC). Gene expression level of 104 tumor cells in 107 normal MNC was defined as 1000 units. Quantitation was based on mean + S.D. of 3 experiments.
